0029734: Modeling Algorithms - Compute global properties of tessellated shape

Browse Source 
New algorithms calculating global properties on mesh data have been added:
- BRepGProp_MeshCinert computes the global properties of polylines represented by a set of points;
- BRepGProp_MeshProps computes the global properties of a surface mesh.

Existing tool BRepGProp now automatically uses new algorithm for triangulation-only faces.
By default, algorithm will use exact geometry objects (surfaces), when it is available (as before the patch);
this behavior can be switched by a new flag UseTriangulation, forcing usage of triangulation instead of exact geometry when both defined.
